This 20 Pesos commemorative from Argentina (issued November 1967, printed by Casa de Moneda) depicts San Martín de Tours, the patron saint of Buenos Aires and one of Christianity’s most iconic charity figures. The artwork by A. Guido illustrates the famous moment where Martin, then a Roman soldier, cuts his cloak to share with a freezing beggar. Rendered in a refined violet tone, the stamp emphasizes themes of mercy, humility, and civic heritage. It remains a desirable mid-century Argentine issue for thematic collectors of religion, saints, and Latin American cultural history.
